CD54/74AC245, CD54/74ACT245 Data sheet acquired from Harris Semiconductor SCHS245B September 1998 - Revised October 2000 Octal-Bus Transceiver, Three-State, Non-Inverting Description The ’AC245 and ’ACT245 are octal-bus transceivers that utilize Advanced CMOS Logic technology. They are noninverting three-state bidirectional transceiver-buffers intended for two-way transmission from “A” bus to “B” bus or “B” bus to “A”. The logic level present on the direction input (DIR) determines the data direction. When the output enable input (OE) is HIGH, the outputs are in the high-impedance state. Features Buffered Inputs Typical Propagation Delay - 4ns at VCC = 5V, TA = 25oC, CL = 50pF Exceeds 2kV ESD Protection per MIL-STD-883, Method 3015 SCR-Latchup-Resistant CMOS Process and Circuit Design Speed of Bipolar FAST/AS/S with Signicantly Reduced Power Consumption Balanced Propagation Delays AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply ±24mA Output Drive Current - Fanout to 15 FAST ICs - Drives 50 Transmission Lines [ /Title (CD74 AC245 , CD74 ACT24 5) /Subject (OctalBus Transceiver, ThreeState, NonInverting) /Autho r () /Keywords (Harris Semiconductor, Advan ced CMOS , Harris Semicon- Ordering Information PART NUMBER CD54AC245F3A CD74AC245E CD74AC245M CD74AC245SM CD54ACT245F3A CD74ACT245E CD74ACT245M CD74ACT245SM NOTES: 1.
